Development process documentation

[Peter Hutterer]

I wrote up what I think is the proposed development process on the wiki.
http://www.x.org/wiki/XServer 

I want this page to be the authoritative source for "how do I contribute to
X" for all testers, developers, maintainers and RM so please help by
updating the information there.

I think there's a few open questions about the process and I'm not sure
about some of the details myself. I'd be great if those who actually were at
XDC could clarify this **on the wiki page**.

Cheers,
  Peter
